Over my last three trips to the lake or other highway destinations I've seen right about 15.9MPG.

I'm between 13.5-14.0 city usually.

City around 13-15

I haven't been on a Hwy trip without towing for awhile, so 9 or 10 Hwy

Wait till the honey moons over...then you will get better mileage, right now, you are enjoying the new sound to much...

So far the DIC indicates about 18.2 mpg since the BB tune (about 300 miles). It was 16.2 before I swapped modules. I'll keep you posted.

UPDATE. This has settled in at around 17.6 MPG. I'm frikkin thrilled! Better performance AND better gas mileage. WIN!
